[Survival of "Pseudomonas aeruginosa" and "Escherichia coli" in cold water (author's transl)].
The survival rates of Escherichia coli and Pseudomonas aeruginosa in water were studied and compared at 4, 10 and 20 degrees C and pH 6 and 8, either separately or in mixed culture at four different concentration ratios. Under ceratin experimental conditions, the temperature, the pH and the bacterial concentration exerted a marked influence on the survival rate. At 4 degrees C, P. aeruginosa may be substituted to E. coli as an effective micriobiological pollution indicator.
